I inherited lots of lovely old roses in my garden from the previous occupant. She probably laid the garden out about 10-12 years ago. I have noticed most of the roses are looking a bit iffy - very woody at the bottom, very spindly branches, making the flowers droop. Could this be because they are getting old (I fed them last winter, but not in the summer this year), or because the winter before, when we moved in, the garden was hugely overgrown and SIL and I chopped lots of it (including roses) to the ground?
They are fab scented old David Austin roses mostly, I'd like to revitalise/save as many as I can.
Thanks for any advice.
